Description

Technical Field

[0001] This utility model relates to the field of material conveying devices, and in particular to a steam generator anti-backfire material conveying device. Background Technology

[0002] A steam generator, also called a steam heat source machine (commonly known as a boiler), is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. The original meaning of "boiler" refers to a water container heated over a fire, while "furnace" refers to a place where fuel is burned. A boiler consists of two main parts: the boiler and the furnace. When using some steam generators, a material conveying device is required for material conveying.

[0003] An existing anti-backfire conveying device for steam generators (publication number: CN221140369U) has at least the following drawbacks:

[0004] In the aforementioned patent, quick disassembly is achieved through a bidirectional screw and a locking block structure, which solves the problem of difficult maintenance of traditional devices and improves maintenance efficiency. However, the locking block structure relies solely on the bidirectional screw for fixation, which may loosen under vibration, posing a risk of the broken steel plate falling off. Furthermore, replacing the broken steel plate as a whole is quite costly. Therefore, it is necessary to propose a steam generator anti-backfire conveying device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steam generator backfire prevention conveying device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A backfire prevention conveying device for a steam generator includes a feeding hopper with several supporting feet fixedly installed on its bottom surface. Several crushing blades are arranged inside the feeding hopper. A PLC controller is fixedly installed on one side of the feeding hopper. The device also includes a replacement assembly located inside the feeding hopper for easy replacement of the crushing blades. The replacement assembly includes a rotating roller located inside the feeding hopper. One end of the rotating roller has several fixing grooves that are movably fitted with the crushing blades. A limiting plate is movably fitted onto the outer circular wall of the rotating roller, and a fixing ring is fixedly fitted onto it. Two first limiting holes are opened on one side of the limiting plate, and two first fixing holes are opened on one side of the fixing ring. Two second limiting holes are opened on the top surface of the fixing ring. A limiting frame is movably fitted inside the second limiting holes. A circular groove is opened on one side of the inner surface of each of the first fixing holes, and a spring is fixedly installed on one side of the circular groove. The spring is fixedly installed on one side of the limiting frame, and the limiting frame is movably fitted into the first limiting hole.

[0008] As a further embodiment of this utility model, the feed hopper is provided with second fixing holes on both sides, and two bearings are fixedly sleeved on the outer circular wall of the rotating roller. A support frame is fixedly sleeved on the outer circular wall of the bearing, and the support frame is fixedly installed on the inner bottom surface of the second fixing hole.

[0009] As a further embodiment of this utility model, a limit ring is fixedly installed at one end of the rotating roller, and a fixing frame is fixedly installed on one side of the feed hopper. The fixing frame is fixedly installed with the support frame located on the right side.

[0010] As a further embodiment of this utility model, a support frame is fixedly installed on one side of the feed hopper, and a drive motor is fixedly sleeved inside the support frame. The drive motor is electrically connected to the PLC controller, and one end of the drive shaft of the drive motor is fixedly installed to the rotating roller.

[0011] As a further embodiment of this utility model, two guide plates are fixedly sleeved inside the feed hopper, and two limiting rings are fixedly installed between the two guide plates.

[0012] As a further embodiment of this utility model, two fixed tubes are fixedly installed on one side of the inside of the feeding hopper. A sensor is fixedly sleeved inside the fixed tube. The sensor is electrically connected to the PLC controller. The two sensors are an infrared flame sensor and a pressure sensor, respectively. A baffle plate is provided on one side of the feeding hopper. Two fixed plates and two L-shaped plates are fixedly installed on one side of the feeding hopper. An electric push rod is fixedly sleeved inside the fixed plate. The bottom surface of the telescopic shaft of the electric push rod is fixedly installed with the baffle plate. The L-shaped plate is movably sleeved with the baffle plate.

[0013] As a further embodiment of this utility model, two support plates are fixedly installed on one side of the feed hopper, and a protective plate is movably sleeved inside the support plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By using the feed hopper, support feet, rotating roller, fixed groove, crushing blade, limiting plate, fixing ring frame, and first limiting hole in cooperation, the crushing blade can be replaced. Simply move the limiting frame and rotate the limiting plate to pull out the crushing blade. The same applies to installation. It also supports replacing the crushing blade as needed, reducing costs by replacing individual crushing blades. At the same time, the limiting frame and limiting plate limit the crushing blade. During use, the limiting frame will not move due to centrifugal force, thus preventing the crushing blade from falling sideways, ensuring safety and convenience. It is quite practical.

[0016] 2. The guide plate guides the material flow, and the limiting ring restricts the material movement path at both ends of the rotating roller to avoid contact with the ends of the rotating roller. When the sensors (infrared flame sensor and pressure sensor) detect backfire, the electric push rod pushes the baffle plate to move downward under the limit of the L-shaped plate to block the danger in time.

[0028] Reference Figures 1-7 A backfire prevention conveying device for a steam generator includes a feed hopper 1, with several support feet 2 fixedly installed on the bottom surface of the feed hopper 1. Several crushing blades 5 are arranged inside the feed hopper 1. A PLC controller is fixedly installed on one side of the feed hopper 1. The device also includes a replacement assembly, located inside the feed hopper 1, for convenient replacement of the crushing blades 5 by the user. The replacement assembly includes a rotating roller 3, located inside the feed hopper 1. One end of the rotating roller 3 has several fixing grooves 4, which are movably connected to the crushing blades 5. The outer circular wall of the rotating roller 3 is movably fitted with a limiting plate 6 and fixedly fitted with a fixing ring 7. Two first limiting holes 8 are opened on one side of the limiting plate 6, and two first fixing holes 9 are opened on one side of the fixing ring 7. Two second limiting holes 10 are opened on the top surface of the fixing ring 7. A limiting frame 11 is movably fitted inside the second limiting hole 10. A circular groove is opened on one side of the inside of the first fixing hole 9. A spring 12 is fixedly installed on one side of the circular groove. The spring 12 is fixedly installed on one side of the limiting frame 11. The limiting frame 11 is movably fitted with the first limiting hole 8.

[0029] When using the device, if the user needs to replace or repair several crushing blades 5 outside the rotating roller 3, the user manually lifts the protective plate 26 to move it out of the support plate 27. Two people work together to push the limiting frame 11 to move inside the second limiting hole 10 and the first fixing hole 9, and compress the spring 12, causing the limiting frame 11 to move inward in the first limiting hole 8. The limiting plate 6 is rotated counterclockwise to rotate the first limiting hole 8. After being released, the limiting frame 11 is supported by the space on the right side of the first limiting hole 8 to prevent the limiting plate 6 from resetting. At this time, the limiting plate 6, after being rotated counterclockwise, no longer obstructs the crushing blades 5. The crushing blades 5 are pulled to move out of the fixing groove 4, completing the disassembly. The rotating roller 3 is rotated to adjust the position of other crushing blades 5 that need to be disassembled. After the new blade is installed in the fixing groove 4, the limiting frame 11 is pushed and the limiting plate 6 is rotated clockwise. After being released, the limiting frame 11 enters the left side of the first limiting hole 8, completing the replacement.

[0030] In this embodiment, the feed hopper 1 has two second fixing holes 13 on both sides. Two bearings 15 are fixedly sleeved on the outer circular wall of the rotating roller 3. A support frame 14 is fixedly sleeved on the outer circular wall of the bearings 15. The support frame 14 is fixedly installed on the inner bottom surface of the second fixing hole 13. A limit ring 16 is fixedly installed on one end of the rotating roller 3. A fixing frame is fixedly installed on one side of the feed hopper 1. The fixing frame is fixedly installed on the support frame 14 located on the right side. A support bin frame 17 is fixedly installed on one side of the feed hopper 1. A drive motor 18 is fixedly sleeved inside the support bin frame 17. The drive motor 18 is electrically connected to the PLC controller. One end of the drive shaft of the drive motor 18 is fixedly installed on the rotating roller 3.

[0031] In use, the rotating roller 3 is laterally limited by the bearing 15 to prevent lateral movement, reduce wear, and extend service life. The other end of the rotating roller 3 is limited by the limit ring 16 to prevent the crushing blade 5 from moving laterally.

[0032] In this embodiment, two guide plates 19 are fixedly sleeved inside the feed hopper 1, and two limiting rings 20 are fixedly installed between the two guide plates 19. Two fixed pipes 21 are fixedly installed on one side of the feed hopper 1. Sensors 22 are fixedly sleeved inside the fixed pipes 21. The sensors 22 are electrically connected to the PLC controller. The two sensors 22 are an infrared flame sensor and a pressure sensor, respectively. A baffle plate 23 is provided on one side of the feed hopper 1. Two fixed plates 25 and two L-shaped plates are fixedly installed on one side of the feed hopper 1. An electric push rod 24 is fixedly sleeved inside the fixed plate 25. The bottom surface of the telescopic shaft of the electric push rod 24 is fixedly installed with the baffle plate 23. The L-shaped plates are movably sleeved with the baffle plate 23. Two support plates 27 are fixedly installed on one side of the feed hopper 1. A protective plate 26 is movably sleeved inside the support plate 27.

[0033] In use, the guide plate 19 guides the material flow, and the limiting ring 20 restricts the material's movement path on both sides to prevent it from contacting the two ends of the rotating roller 3. When the sensor 22 (infrared flame sensor and pressure sensor) detects backfire, the electric push rod 24 pushes the barrier plate 23 to move downward under the L-shaped plate limit to block the danger in time.

[0034] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0035] The feed hopper 1 is equipped with a conveyor mechanism, such as a conveyor belt, at its bottom. Material is fed via the conveyor belt. When the user needs to replace or repair several crushing blades 5 outside the rotating roller 3, the following steps are taken: The user manually lifts the protective plate 26 to move it out of the support plate 27. Two people work together to push the limiting frame 11 inside the second limiting hole 10 and the first fixing hole 9, compressing the spring 12 to move the limiting frame 11 inward within the first limiting hole 8. The limiting plate 6 is rotated counterclockwise, causing the first limiting hole 8 to rotate. After being released, the limiting frame 11 is supported by the space on the right side of the first limiting hole 8, preventing the limiting plate 6 from resetting. At this point, the counterclockwise rotated limiting plate 6 no longer obstructs the crushing blades 5, pulling them from the fixed position. The blade is removed from the fixed groove 4, completing the disassembly. The rotating roller 3 is rotated to adjust the position of the other shredder blades 5 that need to be disassembled. After the new blade is installed in the fixed groove 4, the limiting frame 11 is pushed and the limiting plate 6 is rotated clockwise. After releasing, the limiting frame 11 enters the left side of the first limiting hole 8, completing the replacement and achieving the effect of replacing the shredder blade 5. The shredder blade 5 can be pulled out simply by moving the limiting frame 11 and rotating the limiting plate 6. The same applies to installation. It also supports replacing the shredder blade 5 as needed, which reduces the cost of replacing individual shredder blades 5. At the same time, the shredder blade 5 is limited by the limiting frame 11 and the limiting plate 6. During use, the limiting frame 11 will not move due to centrifugal force, thus preventing the shredder blade 5 from falling off laterally, ensuring safety and convenience in use, and making it quite practical.
